Extremely easy to use and amazingly accurate. Absolute must for phosphate control, great to check your top-off water.

it is costly, but i am glad i got it, it is very acurate, and easy to use once you manage to dump the packet in the cuvature.

I've been using this product for a few months and the only thing I could suggest is that Hanna make a liquid reagent available. Accuracy is right on with Salifert test kit.

This is a huge step up from trying to read different shades of a color. I just can't wait till they bring out other testers

This unit is as close to lab results as you can get. Just 2 simple steps and wait the 3 minutes for the results. Much easier than matching a color to a card.

good productBy Craigon 9/22/2011

I totally like having a digital read out instead of try to match colors like the other test kits, but the Hanna Checker is a little hard to use. You have to be able to open a packet with a wide opening and pour it into a very small hole, in a short amount of time. It comes with two curvettes so I started using one for the "zero" and the other for the phos reading. I still don't like the packets though, it's hard to empty all the contents without spilling reagent powder.

The Hanna Phosphate Checker is a great product that makes testing phosphate so easy and accurate. I tested the unit against another more expensive product and it was spot on in three different tanks. Can't wait to get my Calcium checker and then the Alkalinity...I hear they are also releasing a Magnesium checker as well.
